REDHAT-BUG-2308680

First published: Fri Aug 30 2024(Updated: )

A refactor of the code fetching the list of interfaces for multiple APIs introduced a corner case on platforms where allocating 0 bytes of memory results in a NULL pointer. This corner case would lead to a NULL-pointer dereference and subsequent crash of `virtinterfaced` if virConnectListInterfaces() is called requesting 0 networks to be filled. The bug was introduced in libvirt-10.4.0 and reproduces only on platforms where allocation of 0-length memory returns NULL instead of a valid pointer. Upstream fix: <a href="https://gitlab.com/libvirt/libvirt/-/commit/8dfb12cb77996519901b8d52c754ab564ebd10e8">https://gitlab.com/libvirt/libvirt/-/commit/8dfb12cb77996519901b8d52c754ab564ebd10e8</a>
